An embodiment of the invention discloses a file scanning system to solve the problem that file scanning efficiency is low. The system comprises a client-side and a server-side, wherein the client-side comprises a file upload module, and the server-side comprises a storage server, a file download server and a scanning server. The storage server comprises a database, and the file download server comprises a file download module. The scanning server comprises a file scanning device which comprises a probability calculation module, an ordering module, an extraction module and a scanning module, wherein the extraction module is suitable for obtaining the number K of scanned files and extracting K to-be-scanned sample files high in suspicious probability from ordered to-be-scanned sample files, and K is a positive integer. The scanning module is suitable for scanning the K to-be-scanned sample files and identifying suspicious sample files in the K to-be-scanned sample files. The file scanning system improves scanning efficiency, can identify the suspicious sample files as much as possible, and improves accuracy in scanning the sample files.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to a file scanning system. Background technique [0002] Malicious program is an umbrella term for any software program intentionally created to perform unauthorized and often harmful acts. Computer viruses, backdoor programs, keyloggers, password stealers, Word and Excel macro viruses, boot sector viruses, script viruses (batch, windows shell, java, etc.), Trojan horses, crimeware, spyware and adware, etc., These are examples of what could be called malicious programs. [0003] In order to prevent malicious programs from attacking the computer, it is generally necessary to install anti-virus software on the computer to scan files in the system to identify and kill malicious programs. [0004] In order to quickly identify and kill malicious programs, and at the same time reduce the resource consumption of the client, more and more current security protection software uses...
